FIGHTE, OF NIOKLEVILLE, PENNSYLVANIA.

TELL-COUPLING.

Specification of Letters Patent.

Application filed October 12, 1907. Serial N 0. 397,220.

To all whom it may concern:

Be it known that I, JOHN S. ALDEN, citizen of the United States, residing at Nickleville, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Thill Couplings, of which the following is a specification.

This invention has for its object a simple construction of thill coupling which may be readily adjusted to compensate for any loosening that might be caused by wear and thus prevent the rattling of loose parts which is an objectionable feature incidental to thill couplings ordinarily.

The present invention consists in certain constructions and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view illustrating my improved thill coupling applied. Fig. 2 is a plan view of the coupling. Fig. 3 is a horizontal sectionalview, part of the axle being shown broken away. Fig. 4 is a transverse sectional view on the line 4:4 of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates a thill iron which is formed at one end with a head 2' on each side of which is formed a tapering or conical trunnion 3. The head 2 is designed to be pivotally mounted by means of the trunnions 3 in correspondingly formed sockets 4: in the inner faces of draft lugs 5, 5 and is held in place by a tie bolt 6 provided with a jam nut, said bolt passing through the head 2 and through threaded apertures in the respective draft lugs.

Clips 8, 8 attach the device to the axle 7, said clips passing through openings formed in the axle clip ties 9, 9, on the forward extensions of which the draft lugs are formed.

The trunnions 3 on the head 2 may be more readily inserted in or removed from the sockets etby means of the upwardly extending grooves 10, formed above the sockets in the respective inner faces of the draft lugs and leading into said sockets.

It is to be particularly noted, as best seen in Fig. 3, that each clip tie is formed with two openings for the ends of the clips to extend through. One of said openings is substantially round and approximately fits the respective end or member of the clip, while the opposite opening in the same tie is laterally elongated, as indicated at 11, so as to permit the lateral rocking adjustment of the clips on the axle to bind the clips tightly thereto. The opposing walls 12 of the clip ties are angularly formed, as also best seen in Fig. 3, and the wider portion of one tie is in advance of the axle 7 and is formed with a laterally elongated opening 11, while the wider portion of the other tie extends to the rear of the axle and is formed with its laterally elongated opening 11 in such portion. Thus it will be seen that the openings 11 alternate, that is, one is in advance of the axle and the other in the rear thereof, and that both of said openings 11 are formed in the wider portions of the ties, whereby they are bounded by the greater amount of meta and no weakening effect is produced on the tie by the formation of such openings or slots.

Having thus described the invention, what is claimed as new is:

The combination with the axle and thill of a vehicle, of two axle clips mounted on the axle and axle clip ties, each of which is formed with a draft lug, a thill head provided with trunnions j ournaled in said draft lugs, the clip ties being formed with angularly opposing edges, one tie widening at the front side of the axle and the other tie being widened at the rear side of the axle, and each tie being formed in its wider portion with a laterally elongated opening to receive one member of a clip and being also formed in its other portion with an opening to receive the other member of a clip the draft lugs being formed with threaded apertures and a tie bolt working in said apertures, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN S. ALDEN.
